I too think it is Nolan's best ! Just played it safe here..
I believe
Memento is underrated by many because its a small movie and the story is confusing for many . It's
got none of the features of what the outer world (non-US/western audience)
associates with "Hollywood", like the grand scale ,CGI or sophisticated concepts....
But Memento is the finest expression of Nolan's ability as a "
storyteller" . But in terms of impact as a "
filmmaker" I would put
Inception on top. He had taken Hollywood movies to a whole new plane with it . In a long time I had seen a movie that just made you go
WOW ! Did hollywood just pull that off. ?. The last time a movie had put me in that kind of awe was
the Matrix. But it was a more flawed product .
To pull off a movie of that scale take tremendous
guts and self-belief from the part of the filmmaker. I remember Nolan saying in an Interview that The first 2 Batman movies of his , were an attempt to test the waters of big hollywood cinema , but "inception" was what he had always Aimed for.
The Dark Knight may be considered a better film by many , but
it had the backing of decades of mythology and stories and some of the greatest fictional characters (Batman I think is the greatest hero , with the greatest villians in comics)
already out there for him to tap into !. But "Inception" he built out from the ground up! That took huge guts .
And he, unlike his contemporaries, does his movies by giving full justice to his vision. There is little proof of corporate interference (see Avengers 2 and Joss whedon ) or being flummoxed by the scale/material (as in most Zack Snyder films) or too much pandering to the bottom line (Michael Bay ! ) in Nolans films (although TDKR had a bit of the last ).
This is why Nolan is the only modern filmmakers who now sits in the pantheon of the Kubrick's and Spielberg's and Cameron's. These people have single-handedly pushed the envelope of hollywood and its capabilities (not just in the traditional acting-scripting-direction sense, otherwise Tarantino and many others make it ) time and time again, and cleared the path for many others to follow..
Now coming back to
TDK VS Memento VS Inception
TDK is the
most popular ,most acclaimed and most memorable of the 3 . But as I said above it was not all Nolan. But the other two were.
Inception had many twists and turns added intentionally to it with the sole aim of confusing /convoluting the film. But
Memento on the other hand
has a near perfect explanantion for everything in the film . There are very few holes in the plot and the climax is an absolute stunner . ! So as a film you could put TDK above but
Memento is "NOlan's" best .
Insomnia and Prestige are remakes and interstellar fell short of what it aimed for. I'm expecting a lot from Dunkirk. If it can be Nolans "Saving Private Ryan" he'll consolidate his position on top.
That's pretty much what I tried to do.
